  • How to number JSF error messages and attach number to invalid component

    - by Pich
    I want to number any JSF error messages (e.g. validation, conversion messages) that appears if a user enters invalid input in a couple of input fields. For example like this when the user sends the form: Name cannot contain numbers E-mail is incorrect ----- Form ------ (1) Name: John 13 Doe Age: 30 (2) E-mail: myemail@domain How can I do this?

  • Simple JQuery Validator addMethod not working

    - by tehaaron
    Updated question on the bottom I am trying to validate a super simple form. Eventually the username will be compared to a RegExp statement and the same will go for the password. However right now I am just trying to learn the Validator addMethod format. I currently have this script: JQuery.validator.addMethod( "legalName", function(value, element) { if (element.value == "bob") { return false; } else return true; }, "Use a valid username." ); $(document).ready(function() { $("#form1").validate({ rules: { username: { legalName: true } }, }); }); Which if I am not mistaken should return false and respond with "Use a valid username." if I were to put "bob" into the form. However, it is simply submitting it. I am linking to JQuery BEFORE Validator in the header like instructed. My uber simple form looks like this: <form id="form1" method="post" action=""> <div class="form-row"><span class="label">Username *</span><input type="text" name="username" /></div> <div class="form-row"><input class="submit" type="submit" value="Submit"></div> </form> Finally how would I go about restructing the addMethod function to return true if and false at the else stage while keeping the message alert for a false return? (ignore this last part if you don't understand what I was trying to say :) ) Thanks in advance. Thank to everyone who pointed out my JQuery - jQuery typo. New Ideally, I am trying to turn this into a simple login form (username/password). It is for demonstration only so it wont have a database attached or anything, just some simple js validations. I am looking to make the username validate for <48 characters, only english letters and numbers, no special characters. I thought a whitelist would be easiest so I had something like this: ^[a-zA-Z0-9]*${1,48} but I am not sure if that is proper JS RegExp (it varies from Ruby RegExp if I am not mistaken?...Usually I use rubular.com). Password will be similar but require some upper/lowercase and numbers. I believe I need to make another $.validator.addMethod for legalPassword that will look very similar.

  • Algorithm to compare people names to detect identicalness

    - by Pentium10
    I am working on address book synchronization algorithm. I would like to reuse some code if there exists, but couldn't find one yet. Does someone know about an algorithm that will tell me in numbers/float/procent how much two names are identical. Levenstein distance is not good in this approach, as names and our adddress books are matching the begining of each of the name sections. John Smith should match Smith Jon, Jonathan Smith, Johnny Smith

  • Scared of Calculus - Required to pass Differential Calculus as part of my Computer science major

    - by ke3pup
    Hi guys I'm finishing my Computer science degree in university but my fear of maths (lack of background knowledge) made me to leave all my maths units til' the very end which is now. i either take them on and pass or have to give up. I've passed all my programming units easily but knowing my poor maths skills won't do i've been staying clear of the maths units. I have to pass Differential Calculus and Linear Algebra first. With a help of book named "Linear Algebra: A Modern Introduction" i'm finding myself on track and i think i can pass the Linear Algebra unit. But with differential calculus i can't find a book to help me. They're either too advanced or just too simple for what i have to learn. The things i'm required to know for this units are: Set notation, the real number line, Complex numbers in cartesian form. Complex plane, modulus. Complex numbers in polar form. De Moivre’s Theorem. Complex powers and nth roots. Definition of ei? and ez for z complex. Applications to trigonometry. Revision of domain and range of a function Working in R3. Curves and surfaces. Functions of 2 variables. Level curves.Partial derivatives and tangent planes. The derivative as a difference quotient. Geometric significance of the derivative. Discussion of limit. Higher order partial derivatives. Limits of f(x,y). Continuity. Maxima and minima of f(x,y). The chain rule. Implicit differentiation. Directional derivatives and the gradient. Limit laws, l’Hoˆpital’s rule, composition law. Definition of sinh and cosh and their inverses. Taylor polynomials. The remainder term. Taylor series. Is there a book to help me get on track with the above? Being a student i can't buy too many books hence why i'm looking for a book that covers topics I need to know. The University library has a fairly limited collection which i took as loan but didn't find useful as it was too complex.

    i want to check if string doesnt have more than 5 numbers, i can do it this way Matcher matcher = Pattern.compile("\\d").matcher(val); i = 0; while (matcher.find()) { i++; } However i would like to do it without while(because we are using regex validation framework). I want to be able to match strings like A2sad..3f,3,sdasad2..2

  • Regex to match 0 - 999 but not blank

    - by James Cadd
    I'm working on a regex to match valid integer numbers such as the following: 0 1 99 999 However it should not allow matching an empty string. The closest I can get is: (0)|\\d{1,3} Which to me says a matching string will have either a zero or a series of digits between 1 and 3 characters long. However, empty strings still appear to match this pattern. What's the proper way to exclude empty strings from this regex?

  • How to code a keyboard button to switch between 2 modes?

    - by le.shep20
    Hi! i'm doing a project, i'm not going to details but i will simplify my idea, i'm using Morse Code ( dot and dash) and i have 2 methods: convert_MorseToChar() and Convert_MorseTonum() in the convert_MorseToChar() method there is swich to compare the input from a user which will be Morse codes and mapping it to characters: private String convert_MorseToChar(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "a" break; Case "-...": MorsetoChar = "b" break; Case "-.-.": MorsetoChar = "c" break; Case "-..": MorsetoChar = "d" break; Case ".": MorsetoChar = "e" break; } } and the other method Convert_MorseToNum(), ues the SAME combinations of Morse codes but mapping them to numbers: private String Convert_MorseToNum(ref string Ch) { switch (Ch) { Case ".-": MorsetoChar = "1" break; Case "-...": MorsetoChar = "2" break; Case "-.-.": MorsetoChar = "3" break; Case "-..": MorsetoChar = "4" break; Case ".": MorsetoChar = "5" break; } } now the senario is: there are 2 Textbox, one the user will write Morse codes in it and the other is for the output. The user will write dot "." and dash "-" from the keyboard and press Enter then the program will go to ONE of the 2 methods to convert the Morse codes. Now what tells the program where to go to convert?? my question is: I want to create mode key to swich between 2 modes: MorseTochar and MorseToNum. i want the down arrow key to act like a mode, when a user press the down arrow then it the program will be in MorseToChar mode, when ever the user input the program directly use the method convert_MorseToChar to convert to characters. and when the user press the down arrow agian, the prohram will swich to MorseToNum mode here when ever the user input as morsecode, the program will directly use the method Convert_MorseToNum() to convert to numbers. HOW I CAN DO THAT Pleaaaas!!! help me! Please excuse my English, English is not my native language :)

  • masm division overflow

    - by Help I'm in college
    I'm trying divide two numbers in assembly. I'm working out of the Irvine assembly for intel computers book and I can't make division work for the life of me. Here's my code .code main PROC call division exit main ENDP division PROC mov eax, 4 mov ebx, 2 div ebx call WriteDec ret divison ENDP END main Where WriteDec should write whatever number is in the eax register (should be set to the quotient after the division call). Instead everytime I run it visual studio crashes (the program does compile however).

  • Python regex help

    - by Dormish
    I am trying to make a regex that finds all names, url and phone numbers in an html page. But I'm having trouble with the phone number part. I think the problem with the numbers part is that is searches until it finds the </strong> but in that process it skips people, instead of making a empty string if the person has no phone number ( simply put instead of a list like this: url1+name1+num1 | url2+name2+"" | url3+name3+num3 it returns a list like this: url1+name1+num1 | url2+name2+num3 , with url3+name3 deleted in the process) for url, name, pnumber in re.findall('Name"><div>(?:<a href="/si([^">]*)"> )?([^<]*)(?:.*?</strong>([^<]*))?',page): I am searchin for people in s single very long line. A person could have an url or phone number. An example of a person with an url and a phone number <tr> <td class="lablinksName"><div><a href="/si/ivan-bratko/default.html"> dr. Ivan Bratko akad. prof.</a></div></td> <td class="lablinksMail"><a href="javascript:void(cmPopup('sendMessage', '/si/ivan-bratko/mailer.html', true, 350, 350));"><img src="/Static/images/gui/mail.gif" height="8" width="11"></a></td> <td class="lablinksPhone"><div><strong>T:</strong> +386 1 4768 393 </div></td> </tr> And an example of a person with no url or phone number <tr> <td class="lablinksName"><div> dr. Branko Matjaž Juric prof.</div></td> <td class="lablinksMail"><a href="javascript:void(cmPopup('sendMessage', '/si/branko-matjaz-juric/mailer.html', true, 350, 350));"><img src="/Static/images/gui/mail.gif" height="8" width="11"></a></td> <td class="lablinksPhone"><div> </div></td> </tr> I hope i was clear enough and if any one can help me.

  • Have problems designing input and output for a calculator app

    - by zoul
    Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

  • Berkeley DB java edition, any LGPL or BSD alternatives in Java?

    - by Ali
    Hi All, I am dealing with a huge dataset consisting of key-value pairs. The queries are always in the form of range queries on the key space (keys are numbers) hence any persistent B-Tree like structure will handle the situation. I would like to use BDB-Java Edition but the product is closed source and my company doesn't want to buy BDB-JE License. I am wondering, would you please share your experience with any non-GPL java based key-value storage system. Thanks, -A

  • O(log n) algorithm for computing rank of union of two sorted lists?

    - by Eternal Learner
    Given two sorted lists, each containing n real numbers, is there a O(log?n) time algorithm to compute the element of rank i (where i coresponds to index in increasing order) in the union of the two lists, assuming the elements of the two lists are distinct? I can think of using a Merge procedure to merge the 2 lists and then find the A[i] element in constant time. But the Merge would take O(n) time. How do we solve it in O(log n) time?

  • Distributed sequence number generation?

    I've generally implemented sequence number generation using database sequences in the past. e.g. Using Postgres SERIAL type http://neilconway.org/docs/sequences/ I'm curious though as how to generate sequence numbers for large distributed systems where there is no database. Does anybody have any experience or suggestions of a best practice for achieving sequence number generation in a thread safe manner for multiple clients?
